Here’s a link to a nice article on TPM Uptake from Computer Weekly. Most enterprise computers have a hardware TPM on board, but they are rarely used. Microsoft’s BitLocker is one application that does and I’ve heard Chromebooks use a TPM to protect information in the cloud. However, broad uptake has been slow. This article suggests that might be changing. Furthermore, TCG is introducing the TPM 2.0 shortly that will be more flexible than the current 1.2. Only time will tell.
